What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What difference
ipn [44]

Answer:

Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.

Explanation:

In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.

When a muscle cell demands energy to contract, what happens to ATP?
icang [17]
C. ATP (Adenosine Triphosphate) has three phosphate groups attached. Each one of the groups occupies an extremely high energy bond (free energy that can do work). In muscle contraction, that high-energy bond is broken and the energy is released for muscle contraction. So when the bond is broken, you end up with ADP (Adenosine Dipohosphate) - broken down.
